Once dandelions take root they are very difficult to eliminate. The perennials develop very strong taproots that may extend several feet into the ground. Due to this firm anchorage, no matter how often they are pulled from a flowerbed or are mowed with the lawn, they will soon pop up again. The grooved leaves of the dandelion rise directly above the taproot in a low-lying rosette that helps conduct water toward this important lifeline of the plant, further ensuring its survival.
